Psalm 43 continues the ache of Psalm 42, but it sharpens the prayer. The soul does not merely ask to feel better. It asks God to judge, deliver, send light and truth, and bring it to the holy mountain and altar. St Augustine hears the voice of the Church in pilgrimage, still living among the tares but asking God to separate her cause from the ungodly. In Christ, Light and Truth are not ideas sent from God. They are the Lord Himself, leading the soul to worship.
Psalm 43 (LXX 42) - Send Forth Thy Light and Thy Truth
Psalm Metadata
| Field | Notes |
|---|---|
| NKJV / Masoretic numbering | Psalm 43 |
| Septuagint / Coptic numbering | Psalm 42. After the Septuagint combines NKJV Psalms 9 and 10 as LXX Psalm 9, this Psalm is shifted by one. |
| Accepted author | MT/NKJV has no superscription. Brenton/LXX gives, “A Psalm of David.” This guide notes the LXX heading but does not assign a precise Davidic episode. |
| Period in author’s life | No precise event is named. The Psalm continues Psalm 42’s exile-like longing and moves toward return to God’s altar. |
| Christ prophecy status | Typological and ecclesial fulfillment. Christ is the Light and Truth who leads the Church to the Father. This is not a direct NT quotation of the Psalm, but John 8:12 and John 14:6 illuminate its fulfillment. |
| Coptic lectionary/service use | Local rows preserve printed Psalm 43 references in the Agpeya Third Hour and Veil Prayer, plus Holy Fifty Days Matins/Vespers rows, especially Psalm 43:3 and 43:5. No verified Pascha, Bright Saturday, or special-service row was found for the target Psalm. |
| Numbering issue | The embedded Brenton text is LXX Psalm 42. The Agpeya displays this as Psalm 42 (43), matching this project guide: NKJV Psalm 43, LXX Psalm 42. |
Historical and Scriptural Context
Psalm 43 is short, but it is not small. It has no separate superscription in the Masoretic/NKJV tradition, and its refrain links it tightly with Psalm 42. Brenton’s LXX text gives it a Davidic heading, which the guide preserves without forcing a specific life setting.
The movement is from complaint to worship. The Psalmist asks God to plead his cause, deliver him from the unjust and crafty man, send light and truth, lead him to the holy mountain, and bring him to the altar. The Psalm is the answer to Psalm 42’s thirst: the soul needs not only water, but guidance back into communion.
Geographical Significance ⛰️
The geography is liturgical: holy mountain, tabernacles, altar. The Psalm aims toward Zion and worship. Spiritually, it also describes the Church’s movement from exile to Eucharistic nearness. The place matters because worship is not vague inward feeling. God leads the soul somewhere, into His holy presence.
The Characters 👥
The praying soul. The same troubled soul from Psalm 42, now asking for judgment, deliverance, guidance, and return to the altar.
The ungodly nation and unjust man. The hostile world and deceitful power from which God must deliver His servant.
God. Strength, judge, deliverer, and the One who sends light and truth.
Light and Truth. In the patristic reading, fulfilled personally in Christ, who says, “I am the Light of the world” and “I am the Way, the Truth, and the Life.”
The altar. The place of sacrifice, joy, thanksgiving, and sacramental approach to God.
🕯️ Light from the Word
Psalm 42:1-2, judge me and deliver me
42:1 A Psalm of David. Judge me, O God, and plead my cause, against an ungodly nation: deliver me from the unjust and crafty man. 42:2 For thou, O God, art my strength: wherefore hast thou cast me off? and why do I go sad of countenance, while the enemy oppresses me?
The Psalmist asks God to judge him. That can sound frightening until we understand what he wants judged: his cause. He is asking God to distinguish truth from falsehood, faithful longing from ungodly accusation, and the afflicted Church from the world that mocks her.
St Augustine reads this as the voice of Christ’s Body living in pilgrimage. The Church still dwells among the tares until the harvest. She may share outward sufferings with the ungodly, but her cause is not the same. Augustine’s key insight is pastoral: believers and unbelievers may endure the same weakness, rain, sickness, pressure, and social conflict, but their longing is different.
The line “why do I go sad of countenance?” repeats Psalm 42’s inner ache. Faith does not pretend the face is always bright. But it brings the sad face before God rather than surrendering it to the enemy.
Lesson Guide
- Key phrases: “Believers and unbelievers may share the same suffering, but their longing is different.” “Faith brings the sad face before God.”
- Emphasize: Judgment here is a plea for God to separate truth from deceit.
- Avoid: Turning “ungodly nation” into culture-war commentary.
Psalm 42:3, light and truth lead to the holy mountain
42:3 Send forth thy light and thy truth: they have led me, and brought me to thy holy mountain, and to thy tabernacles.
This is the heart of the Psalm. The soul does not say, “send me a better mood.” It says, “Send forth Thy light and Thy truth.” The problem is not only sadness. The problem is disorientation.
Augustine identifies the Light and Truth with Christ. They are two names, but one reality in the Person of the Lord: “I am the Light of the world” and “I am the Way, the Truth, and the Life.” This is not decorative Christology. It means guidance is personal. God does not merely give information to the soul. He gives His Son.
The Light and Truth do not lead the soul into private spiritual self-absorption. They lead to the holy mountain and tabernacles. Christ leads the soul into the worshipping life of the Church, into repentance, praise, Eucharist, and the communion of the saints.
Lesson Guide
- Key phrases: “The problem is not only sadness. The problem is disorientation.” “Guidance is personal. God gives His Son.”
- Emphasize: Light and truth lead to worship, not spiritual isolation.
- Avoid: Reducing light and truth to information, opinions, or apologetics.
Psalm 42:4, the altar and the God who gladdens youth
42:4 And I will go in to the altar of God, to God who gladdens my youth: I will give thanks to thee on the harp, O God, my God.
The destination is the altar. Augustine’s exposition rises here from the earthly altar to the invisible altar above. He says the one who approaches must separate his cause from the ungodly, and that the worshipper himself becomes the offering. This fits the Orthodox understanding of worship: we do not merely watch a sacrifice. We are gathered into Christ’s self-offering.
“God who gladdens my youth” is not nostalgia. Augustine interprets youth as newness. The old man goes mourning; the renewed man is made glad. In Christ, the soul becomes young not by denying age or suffering, but by receiving new life.
The altar also keeps the Psalm from vague spirituality. The soul’s hope is sacramental. The path from sadness to joy passes through God’s light, God’s truth, God’s holy mountain, and God’s altar.
Lesson Guide
- Key phrases: “The worshipper himself becomes the offering.” “Youth means newness.”
- Emphasize: The altar is the destination of guidance.
- Avoid: Speaking about worship as if it were only personal inspiration.
Psalm 42:5, hope in God again
42:5 Wherefore art thou very sad, O my soul? and wherefore dost thou trouble me? Hope in God; for I will give thanks to him, who is the health of my countenance, and my God.
The refrain returns from Psalm 42, but now the soul has prayed for light, truth, mountain, tabernacle, and altar. Hope is no longer a vague command to cheer up. It is anchored in worship.
The phrase “health of my countenance” is spiritually precise. The face changes when the soul is led back to God. This does not mean instant emotional brightness. It means the countenance is healed from despair, resentment, and scattered desire.
The final words are decisive: “my God.” The Psalm began with opposition and cast-off grief, but it ends with personal belonging. The enemy has not disappeared, but the soul has been re-claimed by worship.
Lesson Guide
- Key phrases: “Hope is anchored in worship.” “The enemy has not disappeared, but the soul has been re-claimed by worship.”
- Emphasize: The refrain is stronger after the altar prayer.
- Avoid: Treating the ending as emotional resolution only.
The Church’s Voice in Worship
The local rows used here preserve printed Psalm 43 references, while the embedded Brenton text is LXX Psalm 42. The Agpeya display form Psalm 42 (43) corresponds to this guide.
- Agpeya Third Hour: The Third Hour includes this Psalm. Its prayer for Light and Truth fits the hour of the Holy Spirit, who illumines the Church and leads her into truth.
- Veil Prayer: The Veil Prayer also includes this Psalm. Its plea to be led to the holy mountain and altar fits late-night watchfulness, when the soul asks to be kept from deceit and led into God’s presence.
- Holy Fifty Days: Local rows include Psalm 43:3 and 43:5 in Holy Fifty Days Matins/Vespers. This is deeply fitting: after the Resurrection, the Church asks the risen Christ, Light and Truth, to lead her into the joy of the altar.
- No verified Pascha, Bright Saturday, or special-service row was found in the available lectionary references for the target Psalm. Its altar and light imagery have broad liturgical resonance, but the exact placements above are the locally verified ones.
Iconography Connection 🖼️
Psalm 43 belongs with icons of the Transfiguration, the Resurrection, and Christ Pantocrator. The Light sent by God is Christ Himself, not merely illumination around Him. The holy mountain points toward Tabor, Zion, and the Church’s ascent into worship. The altar connection also makes this Psalm suitable beside Eucharistic iconography: Christ the High Priest, the heavenly altar, and the Church offering thanksgiving in Him.
Spiritual Fruit 🍇
- Ask for Light and Truth before asking for relief. A sad soul often needs guidance more than immediate comfort.
- Let Christ separate your cause from deceit. Do not define yourself by the enemy’s accusation.
- Return to the altar. Private prayer is essential, but the Psalm’s destination is worship.
- Receive newness. The God who gladdens youth renews the inner person even when circumstances are old and heavy.
- Preach hope after prayer, not instead of prayer. The refrain has power because the soul has first asked to be led by God.
Teacher's Notes
- Timing: 70 to 80 minutes.
- Where to linger: Verse 3 and verse 4.
- Where to compress: Verse 1’s hostile language can be explained briefly and pastorally.
- Key phrase to say slowly: “Guidance is personal. God gives His Son.”
- Pastoral warning: Avoid turning this Psalm into a generic lesson on optimism. Its hope is ecclesial and sacramental, grounded in Christ and the altar.
- Accuracy note: MT/NKJV Psalm 43 is unsuperscribed, but Brenton/LXX gives “A Psalm of David.” The project title follows NKJV numbering, while the Scripture block follows LXX Psalm 42.
